EDWARD P. COBB-Y, OF ST. LOUIS, MISSOURI.

VAPOR BURNER.

SPECIFICATION forming part of Letters Patent No. 286,267, dated October 9, 1883.

Application filed December 28, 1882.

To all whom it may concern.-

Be it known that I, EDWARD 1?. Corner, of

St. Louis, Missouri, have made a new and usewhich-- Figure 1 is'a vertical section of the improved burner; Fig. 2, a plan; Fig. 3, a section on the line 3 3 of Fig. 1; and Fig. 4, a front elevation,

. showing the valve-crank.

The same letters of reference denote the same parts. e

The present invention relates to the means for more effectually directing the blaze upon the retort in priming the burner.

A represents a Vapor-burner in which the present improvement is embodied. The vapor flows into the passage 13; thence, in' place of entering the upright passage O immediately, the vapor passes into a circuitous passage, D, which winds around the passage 0, as shown in Fig.3, and then passes upward at D, and

finally leads into the horizontal passage E, which in turn leads into the passage C. After reaching the passage O by the route described,

the vapor escapes to the burner in the usual manner.

In place of regulating the flow of the vapor by means of the customary needlc-valve, F, it is controlled by a valve, G, which works in the passage E, seating at a point, g, therein between the passages D O. The needle-valve F is designed for cleaning purposes. A gummy deposit gradually forms in the orifice 0, through which the vapor escapes from the tube 0, and h to remove this deposit the needle-valve F is occasionally used 5 but as the frequent use of the needle-valve causes it to wear to such an extent as to be an unreliable means for stop ping the flow of the vapor, the blunter valve G, which, from its shape, is more durable, is

.rected.

to the burner I.

(No mode-1.)

H the heat of the burner is conducted to the tube E, and thence to the tube 0. The valve G is operated by means of the crank G, by turning which the valve is suitably moved in the tube E.

I have ascertained that in the ordinary burner the blaze of the oil burned at and about the orifice c for the purpose of initiating the vaporizing of the oil is not eifectively di To improve a vapor-burner in this respect,I employ means for spreading the blaze and deflecting it more against the retort of the burner. A convenient means for this is the rod L, which is held in suitable bearings, Z Z, and adapted to be moved, when desired, over the'orifice c, as indicated by the dotted lines in Fig. 1, in. which position it operates to spread the flame, preventing the flame and heat from passing directly upward to the burner, and directing it against that part of the construction wherein the oil is received and vaporized. As soon as the burner has become sufficiently heated and is self-operative, the rod L is withdrawn, as shown in the full lines in Figs. 1, 2, t'romabove the orifice 0, allowing the vapor to escape directly upward The rod L, at its outer end, may serve, as indicated in Fig. 4, as a stop to limit the movement of the crank G.

The present improvement is preferably associated with a rcto rt, M, and vapor-reservoir N, such as shown in Fig. 1, and described more particularly in a pending application, No. 80,350, for Letters Patent. The deflector L is especially useful in combination with this form of retort and with the vapor-reservoir N.

1. In a vapor-burner having a retort,'M, and an oil-reservoir, N, directly overhanging the burner, passage 0, having the orifice c, the passage B, the surrounding and vertical passages D, D, and E, and valves F and G, regu lating the supply of gas and size of flame, sub stantially as described. I i

2. Ina vapor-burner having a burner,yI, the flame-orifice c, the oil-supply passages D, D, E, and B, the overhanging reservoir N and. retort M, and the deflector L, operating to deflect the flame at will on the under surface of N, substantially as described.
